Miley Cyrus has gone nude for Marc Jacobs, but it's all for a good cause. The 20-year-old celeb is helping raise awareness for skin cancer by posing nude on a T-shirt designed by the famed designer. Jacobs has accrued a list of notable celebrities to strip down for his campaign, including models Naomi Campbell, Heidi Klum, Marissa Miller and Kate Upton as well as designer Victoria Beckham.

The shirts simply read, “Protect the Skin You’re In,” with an image of celebrities. Proceeds from the shirts will go toward melanoma research at the NYU Cancer Institute and NYU Langone Medical Center.

Cyrus tweeted an image of the shirt, along with information about where to purchase them. "Ts are available at 9 Marc Jacobs boutiques including SanFran, LA, Chicago, New York, Boston & Savannah GA! [sic].”[[nid:1361293]]

Her modesty is covered by the strategically placed slogan, and she has her hands covering her lower half.

The shirts retail for $35 and the campaign has already raised more than $1 million for the NYU School of Medicine's Interdisciplinary Melanoma Cooperative Group.

"The public awareness generated by the T-shirt campaign is enormous, not to mention the funds that have been raised," Dr. William L. Carroll, director of the NYU Cancer Institute, said. "We are grateful for the generosity of Marc Jacobs and Robert Duffy in allowing the NYU Cancer Institute to focus on research and advancing clinical care."
